They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

The WiFi did not work three hours of productivity lost. 15 people from the firm were on the flight. Loss of revenue

Very rude stewardess; there was a senior citizen woman next to me who asked the stewardess for help getting her purse out of the overhead bin, and it was as though she asked the stewardess for $1M . . . . I was shocked how rude that stewardess was. The stewardess also refused to get the senior citizen woman a drink about half way thru the flight, telling her that we were almost landing . . . . that stewardess made my flight (and in particular the flight of the senior citizen next to me) very uncomfortable

Overall good experience...exception: very cold temp in teh cabin.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

It would have been better if the flight was on time

It was good. Last flight was delayed but I always say that is in God's plan

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The seat was not comfortable. 1D. My back was sore all night and the next day.

It is not a good experience with Copa Airlines: flight delay, luggage delay, etc.

We where skipped for this flight will not head to Panama until tonight..

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

Placed us in the last rear row of the plane so could not recline seats because of the rear wall, and also made it more of a tight space when the passenger in front reclined their seat. While understand seat assignments, every passenger should be afforded a reclining seat. The odor control scent from the restrooms was overwhelming strong. My wife and I could not deal with it, and she suffered a terrible headache as a result. I kept getting hit by the crew since I was on the ilse seat. No apologies, nothing. They made me feel like I was supposed to take the beating for a 3 hr flight.

Check in person said there would be lunch. We were first class passengers and lunch was chips.

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

The plane left over an hour late. I missed my connection going to Tokyo. They haven’t sent my bag to Thailand, where I ended up. It took me over 32 hours to get here. Very bad experience so far. I hope they can fix this and get my bag to me, within 24 hours it doesn’t look good at this time.

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

It was soooo hot I was sweating even at altitude. I know you want people to sleep, but keeping it that hot is stupid!

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

I contacted both carriers months beforehand to change the cabin (booked in April) but to no avail (united asked to contact Swiss since it was their equipment, Swiss told me to reach out to united). So yeah… My seat was pretty worn down, legroom on 27K was more than enough, but still economy seating so, getting to know your neighbours was easy. According to ground staff, the flight was massively overbooked- and this showed. I ordered a gluten free meal beforehand (which was honoured) but for breakfast got a bread roll and croissant 🤷🏼‍♂️ The connection itself is great. Leaving SFO late PM to arrive at ZRH in the afternoon makes it easier to get re adjusted again. However, and since I’ve flown this connection a couple of times in the past, I will rather deal with one carrier only and include a layover on the east coast.

The crew was friendly and helpful. The entertainment system in my row did not work for movies and TV shows and the Direct TV cut off in parts and stopped showing the baseball playoff game.

Non-stop commercials were frustrating when trying to view direct TV

Forced to check bag, even though plenty of space in overhead bins. Did not appreciate having to wait at baggage claim to retrieve suitcase.

Great. I was in mint class. Security was spectacular. A lot of room on the flight! And the WiFi worked this time- it didn’t work the last time and I am on a business trip so that was a problem.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

I liked the punctuality, the crew, and overall the whole flight

Boarding was fast, easy, and we landed early. The entertainment system was very buggy and kept resetting throughout the flight.

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

The crew in the Vegas airport clearly was having a bad day … they moved on and the crew that checked us in for boarding was great, as was the flight crew. I did get the wheel of my carry on stuck in the overhead bin. Amazing team effort to include the flight attendants, the pilot, and another pilot who was on the flight as a passenger. Finally got it unstuck ✅

My seat was defective. The suppor was broken under the cushion so I road on metal for 4 hours

I always looks forward to the Biscoff cookies and they weren’t offered….

Inflight wifi was awful. Couldn't connect for the first hour until they manually reset, and after that the connection kept dropping every five minutes. Their entertainment option streamed fine but normal browsing was unusable.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.
